I'm happy to annnounce a new version of GNU Nettle, a low-level
cryptographics library. The Nettle home page can be found at

NEWS for the 2.7 release

        This release includes an implementation of elliptic curve
        cryptography (ECC) and optimizations for the ARM architecture.
        This work was done at the offices of South Pole AB, and
        generously funded by the .SE Internet Fund.

        Bug fixes:

        * Fixed a bug in the buffer handling for incremental SHA3
          hashing, with a possible buffer overflow. Patch by Edgar
          E. Iglesias.

        New features:

        * Support for ECDSA signatures. Elliptic curve operations over
          the following curves: secp192r1, secp224r1, secp256r1,
          secp384r1 and secp521r1, including x86_64 and ARM assembly
          for the most important primitives.
        * Support for UMAC, including x86_64 and ARM assembly.

        * Support for 12-round salsa20, "salsa20r12", as specified by
          eSTREAM. Contributed by Nikos Mavrogiannopoulos.

        * ARM assembly code for several additional algorithms,
          including AES, Salsa20, and the SHA family of hash

        * x86_64 assembly for SHA256, SHA512, and SHA3. (SHA3 assembly
          was included in the 2.6 release, but disabled due to poor
          performance on some AMD processors. Hopefully, that
          performance problem is fixed now).
        The ARM code was tested and benchmarked on Cortex-A9. Some of
        the functions use "neon" instructions. The configure script
        decides if neon instructions can be used, and the command line
        options --enable-arm-neon and --disable-arm-neon can be used
        to override its choice. Feedback appreciated.
        The libraries are intended to be binary compatible with
        nettle-2.2 and later. The shared library names are and, with sonames still and (soon)

Happy hacking,
